What it protects against
Bordetella bronchiseptica is a bacterium behind much of what is called kennel cough, a contagious cough that spreads between dogs sharing air. It is rarely dangerous for a healthy adult dog but is miserable, spreads through a kennel in days, and can be serious in puppies and older dogs. Kennel cough is caused by several agents, so the vaccine reduces the risk rather than removing it.
Three forms
- Intranasal — drops in the nose, one dose, protection within a few days. The most common form for boarding.
- Oral — a dose in the mouth, one dose, similar timing.
- Injectable — two doses two to four weeks apart the first time, then a single annual booster.
How often
Annually is standard. Some kennels and daycares require it every six months, so check the policy of the place you use.
Timing before boarding
Give it at least a week before a stay: protection takes a few days, and the intranasal form can cause a mild cough or sneeze for a day or two, which a kennel may mistake for the real thing at drop-off.
